Actual result: -------------- nothing, except a new line in my apache error_log file : [Thu Aug 26 00:00:18 2004] [notice] child pid 3877 exit signal Segmentation fault (11) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29843&edit=1
